-''To the participants of A3F-CNSSS20'' (2020-08-18)~
Some new input samples and external files are uploaded on [[the A3F-CNSSS20 room>A3F-CNSSS20]].
-''To the participants of A3F-CNSSS20'' (2020-08-15)~
&color(red){Please re-download [[pikoe1.f90>#latest]] to properly perform the momentum distribution calculation (when IVAR=9).}; The result of the test below is not affected at all by this change.
-''To the participants of A3F-CNSSS20'' (2020-08-07)~
Please complete the following test by the summer school. Because I must concentrate on the preparation for my lecture, I will not be able to respond to any question/request for a while. Thank you for your kind understanding. (K. Ogata)
++Read this page carefully.
++Download pikoe1.f90, FLtbl_rede.dat, EDAD1p12C_e.dat, EDAD1p11B_e.dat, and 12Cp2p11Bgs_set1_cs.cnt.
++Compile pikoe1.f90 and run the executable file with redirecting 12Cp2p11Bgs_set1_cs.cnt.
++See tbl_12Cp2p11Bgs_set1_cs.dat and plot "tdx" as a function of "th2l" given in the file.
++You will get a result like &ref(files/12Cp2p11Bgs_set1_cs.pdf,this);. (Experimental data are also plotted in the figure.)

*What's this page? [#intro]
A computer code "pikoe" for proton-induced knock-out reaction calculations for exclusive processes can be downloaded from this page. Some instruction, updates, and FAQ are also available here.
*About the program [#program]
***Language [#lang]
Fortran 90 (complete program).
***Notice [#notice]
Copyright belongs to the following persons. &color(red){Please do not redistribute the files or make them public};.

-Kazuki Yoshida (ASRC, JAEA / RCNP, Osaka U)

&color(red){If you present or publish results obtained by pikoe, please cite it as follows.};~
K. Ogata, K. Yoshida, and Y. Chazono, computer program pikoe (unpublished).
We are planning to publish pikoe in Computer Physics Communications. Once it is done, we announce it on this page.
***Usage [#usage]
+Prepare an input file (a manual and samples are given below) and, if necessary, external file(s).
+Compile pikoe1.f90~
In some cases, you may need to put an option (see below).
+Run pikoe1 with redirecting the input file. For example,
pikoe1 < 12Cp2p11Bgs_set1.cnt
In some environment, you must type
./pikoe1 < ./12Cp2p11Bgs_set1.cnt
***Error! [#error]
If pikoe does not run successfully, try the following.
-Read carefully the output. In many cases, the reason for the error is given. Correct your input file and/or external file(s) accordingly.
--If it is written that the size of an array is not enough, you need to change the parameter(s) given in "module dims" in the source file.
-Put a compiler option that specifies SAVE statement for every local variable and array.
--gfortran: -fno-automatic
--ifort: -save (Unix/Linux/OS X) or /Qsave (Windows)
-Make stacksize larger.
--On the RCNP high-performance computing system, you can put
ulimit -s unlimited
in your batch file.
--If you use Intel compiler on windows, you can add
-link /stack:***
when you compile pikoe1.f90 (*** is the stacksize in bytes).

***Latest version [#latest]

source file of pikoe version 1~
&color(red){NOTE: The 200807 version was found not to calculate the &mathjax{d\sigma/dP_x}; and &mathjax{d\sigma /dP_{\rm tot}};, which has been corrected in the 200815 version. This bug-fix does not affect any numerical result you obtained with the 200805 version. For this reason, we have decided not to give a different version # to the revised source code. Thank you.};
