## DWBA & Monte Carlo Simultion

### DWBA and Ex List:

For 2-nucleon transfer, Orbital take the form NL=X, where N is number of node, X is momentum number. n and L are related by Σi (2ni+li) = 2N + X + 2n + l, where ni and li are the principle number and orbital angular momentum of the each transfered nucleon, and n and l are the internal quanta of the 2-nucleon. e.g. (t,p) reaction to 0f orbtial, the left-hand side would be ni = 0 and li = 3 and the sum is 3+3 = 6 = 2N + X + 2n+l. Assume n = l = 0, we have 6 = 2N+L. Thus, 3L=0, 2L=2,1L=4, 0L=6. Beam Jπ:

HELIOSmatics was first built by Ben P. Kay in MS Excel around 2010. It was modified by Ryan Tang later. And now it migrated to the web on Dec, 2022.
The calculation can be found in the source code (heliosmatics.js or press F12)
