Hydrogen recombination lines near 327 MHz - II: A Galactic plane survey with a 2 degrees x 6 ' beam

In a previous paper we presented a low-resolution (2 degrees x 2 degrees) s urvey of radio recombination lines (RRLs) at 327 MHz in the longitude range l = 330 degrees to 0 degrees to 89 degrees. In this paper, we present the results of a higher resolution (2 degrees x 6') survey of RRLs from seven 2 degrees -wide fields and two 6 degrees -wide fields in the same longitude range. Observations were made using the Ooty Radio Telescope (ORT). A total of 252 spectra that were obtained are presented. RRLs were detected in alm ost all the individual positions within the fields with l < 35<degrees> and at several individual positions within the fields in the longitude range l = 35 degrees to 85 degrees. Detailed analysis of the data towards the held centered at G45.5+0.0, shows that the line emission consists of discrete z ones of ionized gas. The angular extent of these zones are Likely to be one degree or more corresponding to a linear size of > 110 pc at the kinematic distance.
