Summary:In papers (Krejčiřík D. et al.: J. Phys. A: Math. Gen.: 39 (32), 10143–10153 ( 2006 ); Krejčiřík D., Tater M.: J. Phys. A: Math. Theor. 41 (24), 244 ( 2008 )) a new very simple -symmetric model was introduced and closed formula for the metric operator was found. We use an alternative integral form of this metric operator to study the spectrum of the metric.
