Nature of problem:
Evaluation of total and differential cross sections in absolute and normalized form for (a,a), (a,a'), (a,b), (a,gamma), (a,gamma-gamma), (a,bgamma) and (a,bgamma-gamma) processes in j-j coupling formalism using statistical compound-nucleus theory, with spin-orbit interaction and/or the Moldauer level-width fluctuation correction if desired. As a generalization of its predecessor, "MANDYF" (CPC 2 (1971) 272), the program has been extended to cater for radiative capture (in observed or competing transitions), to take account of competing channels to a continuum of residual states, and to automatically calculate any required transmission coefficients from prespecified optical-potential parameters. It is capable of furnishing data for twin-level resonance calculations and evaluating magnetic substate populations from gamma- distribution parameters.

Solution method:
Akin to "MANDYF", but with modified organization, the program tabulates momenta permitted by selection rules, calculates penetrabilities, and builds products of these with appropriate Racah factors to generate Legendre-polynomial expansion coefficients. Thence total and different- ial cross sections are evaluated in absolute and normalized form automatically.

Restrictions:
Dimensional restrictions commensurate with storage capacity dictate that incoming and outgoing orbital momenta be l<= 8 and the number of extra channels be O3<= 40 in the present version (readily capable of extension).
