Abstract: (arXiv)

An exactly solvable many-particle quantum system is proposed by adding some nonhermitian but PT invariant interactions to the

B_N

Calogero model. We have shown that such extended

B_N

Calogero model leads to completely real spectrum which obey generalised exclusion statistics. It is also found that the corresponding exchange statistics parameter exhibit `reflection symmetry' provided the strength of a PT invariant interaction exceeds a critical value.
