Secondly, the shell model does not provide a scheme for nuclear reaction theory whereas the supennultiplet scheme is applicable to reaction channels as discussed for example by John and Seligman pO 74]. We shall presently describe the scheme used in the resonating group method introduced by Wheeler [WH 37, WH 37a] and developed in full detail by Wildennuth and other authors [WI 77]. This scheme provides implicitly a supennultiplet model space which can be made explicit by use of the concepts described in this section.

3 Irreducible Representations of the Symmetric Group SIn) 21 The next proposition deals with the reduction of the representation d f of S (n) when this representation is restricted or subduced to its subgroup S (WI) X S (W2). 28 Proposition: The irreducible representation d f of S (n) for f = [fl f2 ... fj] under subduction to its subgroup S (w I) X S (W2) reduces into the irreducible representation dfl X d 1w21 if and only if fl = [f11 f21 ... fj II] is a solution of the inequalities fl ;> f11 ;> f 2 ;> f:u ;> ...
